High-Protein Steak Fajita Bowl How to Make It (Step-by-Step Method)

1. Prepare the Steak

Pat the steak dry with paper towels. This helps create a proper sear rather than steaming.

In a small bowl, mix cumin, smoked paprika, chili powder, oregano, half the salt, and black pepper. Rub the spice blend evenly over both sides of the steak. Let it sit at room temperature for 10 minutes while you prep the vegetables.

2. Sear the Steak

Heat 1 tablespoon olive oil in a large skillet or cast-iron pan over medium-high heat. Once the pan is hot and shimmering, add the steak.

Cook for 4–5 minutes per side for medium-rare (internal temperature around 130–135°F / 54–57°C), or adjust for preferred doneness. You’re looking for a deep brown crust with slightly charred edges.

Remove from the pan and let rest for 5–8 minutes before slicing. Resting allows juices to redistribute, keeping the meat tender and juicy.

Slice thinly against the grain for maximum tenderness.

3. Cook the Fajita Vegetables

In the same skillet (no need to wash it — the steak drippings add flavor), add the remaining tablespoon of olive oil.

Toss in sliced onions and cook for 2–3 minutes until they begin to soften. Add bell peppers and sauté for another 4–6 minutes, stirring occasionally. You want them tender but still slightly crisp, with light charring along the edges.

Add minced garlic during the final minute and stir until fragrant. Sprinkle with the remaining salt.

Remove from heat and squeeze fresh lime juice over the vegetables.

4. Warm the Beans and Base

While the vegetables cook, warm your rice and black beans separately. If using brown rice, ensure it’s fluffy and hot. You can microwave for 1–2 minutes or heat gently in a saucepan with a splash of water.

Stir a bit of lime juice and chopped cilantro into the rice for extra flavor.

5. Assemble the Bowls

Divide rice evenly among serving bowls. Top with a scoop of black beans, then arrange sliced steak on one side and sautéed fajita vegetables on the other.

Add sliced avocado, a dollop of Greek yogurt or sour cream, and a sprinkle of shredded cheese if desired. Finish with extra cilantro and a squeeze of lime.

Serve immediately while everything is warm and vibrant.

High-Protein Steak Fajita Bowl Serving Suggestions

This High-Protein Steak Fajita Bowl is perfect for family-style serving. Arrange all the components in separate bowls on the table and let everyone build their own creation. Place the steak slices in a wide platter so the charred edges are visible, nestle the colorful peppers and onions beside it, and keep rice and beans warm in serving dishes. Offer toppings like diced tomatoes, sliced jalapeños, shredded lettuce, salsa, and extra lime wedges. This interactive setup makes dinner fun, especially for kids who love customizing their plates.

For a lighter or low-carb variation, swap the rice for cauliflower rice or shredded lettuce to create a fajita salad bowl. You can also serve the steak and veggies in warm whole-wheat tortillas alongside the bowls for a hybrid taco-night option. If hosting guests, garnish each bowl neatly with avocado slices fanned across the top and a sprinkle of fresh herbs for a restaurant-style presentation. Pair with sparkling lime water or a fresh fruit salad for a balanced meal that feels both indulgent and wholesome.

High-Protein Steak Fajita Bowl Storage + Meal Prep

This recipe is ideal for meal prep because all components store well separately. Keep steak, vegetables, rice, and beans in airtight containers in the refrigerator for up to 4 days. Store avocado and yogurt separately and add fresh when serving to maintain texture and flavor.

To reheat, warm rice, beans, and vegetables in the microwave for 1–2 minutes, stirring halfway through. Reheat steak gently to avoid overcooking — 30–60 seconds at a time works best. Alternatively, warm everything in a skillet over medium-low heat with a splash of water.

The steak can be frozen for up to 2 months, though the vegetables are best enjoyed fresh. Refresh leftovers with fresh lime juice, cilantro, or an extra spoonful of yogurt to revive brightness. These bowls make satisfying grab-and-go lunches that stay flavorful and filling throughout the week.
